This paper presents an environmental impact assessment of the entire cycle existence tube-vacuum solar collector prototype. The innovativeness solution involved using a phase change material as heat-storing material, which was placed inside collector’s tubes-vacuum. PCM used in this study paraffin. system boundaries contained three phases: production, operation (use phase), and disposal. An eco...

Bioethanol is the most widely used biofuel in world. production from biomass a way to reduce crude oil consumption and environmental pollution. This work aims evaluate potential impacts of bioethanol corn stover obtained phytoremediation, comparing four different acids (Sulfuric, Nitric, Hydrochloric Acetic acids) perform pre-treatment. The study follows life cycle thinking perspective, account...

Over the past 40 years, development of Ceramic Matrix Composites (CMCs) has focused mainly on improvement material performance and optimization cost-efficient production routes. Recently, more fields application have opened up for CMCs, in which environmental impacts are relevant. These barely been investigated so far but receive growing interest due to increasing awareness consequences. Our in...

Abstract One of the biggest energy consumers and CO2 emitters in world is steel sector. With growth infrastructure construction, output has risen year over year. Therefore, a life cycle assessment inputs outputs at each stage manufacturing process necessary to enable adoption management offer sustainable production consumption. The Life Cycle Assessment method employed this study assess environ...

Goal, Scope and Background. Ronozyme® P5000 CT is an industrially produced enzyme product (phytase) which is able to degrade naturally occurring phytate in animal feed and release the phytate's content of phosphorus for pig's growth. Ronozyme P5000 CT (hereafter called Ronozyme Phytase) can be used as an alternative to inorganic phosphorus supplementation to feed and the study addresses the env...

This study focuses on the life cycle assessment (LCA) of an onshore wind farm in India. The is conducted 10 Vestas 1.65 MW turbines situated Karnataka state Following ISO 14044 standard, SimaPro LCA software used to model process. functional unit chosen as 1 MWh sent out electricity. results cycle-based emissions are compared with those coal power plant. global warming potential found be 11.3 g...

Glass foams is an interesting option for the use of fractions glass cullet otherwise destined to landfills. As building insulation materials, obtained by conventional processes have still some drawbacks in purity starting feedstock, which can be avoided implementing alkali activation process. Using life cycle assessment methodology, research analyses potential impacts associated foam from waste...

By posing the question of what will be definition sustainable development in future, it can almost seen that principle “no waste” and production new materials with less a negative environmental impact have high priority. To further develop environmentally friendly materials, is necessary to know about drivers as well evaluate effects conventional construction. According definitions characterist...

Are small-scale wind turbines green? In this study, we perform a ‘cradle to grave’ life cycle assessment of novel domestic-scale 10 kW vertical axis turbine tree which uses combined Savonius and H-Darrieus blades. Situated at test site in Surat Thani, Thailand, SimaPro software was used evaluate the environmental impact profile tree. Comparisons Thai grid mix were made, using both with without ...
